Hot water System - Case Study Example

Hot water System Question: 2. Refer to the drawings for the Spring Valley project. What type of pipe systems are specified for the following systems 2. The type of pipe system in the drawing of the Spring Valley Project is a domestic water below grade if the organisation of the pipes is anything to go by. Question3: 3. Describe each of the five step processes you would use to size the domestic water distribution system for a commercial building. 3. The five step process and conditions to consider while sizing a domestic water distribution for a building such as a commercial building: Firstly it would be of utmost importance and vital to consider the initial cost for the booster sets as a totality. This is to mention that it includes all the aspects and components of the booster set which are critical for the proper functioning of the whole system. They include the pumps, control panels, frequency converters, diaphragm tanks and pressure sensors. It would be logical that we consider the financial cost in the same respect and line of thought. It is the initial cost of tanks, pipes, valves and tanks, this would be proper to infer the same actions. Similarly, it would be critical to consider the maintenance cost of the same building. Energy cost is another implication that cannot escape attention in this stage and step. Subsequently, it refers to the condition where the lost revenue or the cost of production for the water system pipes ought to be considered as such. Question 4: 4. Describe the process you would use in sizing the storm water drainage system for a commercial building? Assume that this buildings dimensions are 100’ x 200’ and that the roof will be tapered such that there are two low points, each of equal square footage. What size roof drains are needed? You need to coordinate with the site contractor to determine what size storm water main to run to the front of the building; describe the process you would use to determine the storm water main size and identify the size. 4. It is important to note the system pressures where isolation valve, regulating assemblies and the static pressures at the plumbing zones. A critical roof tank solution is to ensure that the mains water is sufficient and enough to cover or supply the whole building, and thus the aim would be ensure sufficient upward and downward pressure. Question: Section 3: Refer to the Spring Valley plans in D2L (hard copy that was handed out in class) and answer the following questions regarding the Drainage, Waste, and Vent systems. (30 Points) Question: 1. Describe the process you would use to determine the total drainage fixture unit (DFU) load on the building sewer for each of the two buildings. What is the total DFU load for each building? (10 points). Referring to the Spring Valley plan the drainage fixture unit it would be important to use the DWV method or the drain, water and vent technique. Thus, each type of a fixture must have to be assigned value for the supply and drain (Daniel, 3). Thus, a cumulative total would be obtained for the water supply fixture units and the vertical column drainage fixture units. In this case, DFU would be a sum of DWV for the whole project. Question: 2. Describe the process you as the project manager would use in determining what materials to use for the DWV systems for this project. (10 points). 2. As a project manager I would consider the cost factors before deciding the materials to use in DWV. The energy cost, initial cost, maintenance costs, durability of the materials and their natural appeal as critical factors in the decision making process of the project. Question: 3. List the plumbing fixtures and/or appliances used in this project (include both buildings). (10 points) A. What is the drain size connection for each? 3. The plumbing fixtures and/or appliance used in the project include and their sizes are approximately, bidet 1 1/2, bar sink 1 1/2, floor drain 2 inches, lavatory 2 inches, water closet with flushometer 3 inches, water closet with gravity tank 3 inches. Question: B. what is the vent size? B. vent size is same to the plumbing fixtures calibrations Question: C. what is the total quantity of each type of fixture or appliance? (10 points) C. the total quantity of each appliance is a sum of private and public installations for all the appliances would be 10inches which is the total of the appliances and plumbing fixtures. Question: Section 4: Refer to the Spring Valley plans in D2L (hard copy was handed out in class) and answer the following questions regarding the Domestic Water Distribution System. (30 Points) 1. Describe the process you would use to determine the total water supply fixture unit (WSFU) load on the domestic water distribution system for each of the two buildings. What is the total WSFU load for each building? (10 points) Section 4: the process of determining the WSFU is based on the private and public installations of the plumbing fixtures and appliances. It would be 1 WFSU=1 GPM= 2 liter/min. Question: 2. Describe the process you would use to size the domestic hot water system for this project. What is the total hot WSFU load for each of the two buildings? (10 points) 2. In order to size the domestic hot water system I would consider the pressure limits, the presence of the valves, sensitivity to electrical fallouts, power consumption, manageable pressure zones and the general cost of operation. The WFSU is same for each of the two building at 2 liter/min. Question: 3. Describe the function of the following as it pertains to the domestic hot water system (10 points) 3. WH-1 refers to water heaters system zone pumps which are responsible for pumping the heated water to the intended destinations. It implies the place where the water is heated and pumped through the valves and vents to the required places b. DET-1- domestic hot water system refers to the liquids boiled and subjected to heat for subsequent usage c. WS-1- Water system is the whole concept of how water is introduced to the building, its usage and how it would be expelled from the building in the consequent times. d. DP-1- differential pressure refers to how the pressure is controlled and dispensed as a system within the building. Work Cited Daniel, Lewy. "Hot water system."
